10 Claims.

This invention relates particularly to Amanifold sets of forms interleaved with carbon-slips, and to a method of manufacturing the same.

The record-slips are provided at one edge 5 with detachable binding-strips which are secured to the corresponding margins of the interleaved transfer-slips (carbons) The transfer-slips are relatively short, so that the free margins of the record-slips may be gripped at the edge opposite l the bound edge. Thus, the user may grip the bound margins with one hand and the free margins of the record-slips with the other, and snap-out the set of transfer-slips, the bindingstrips being at the same time detached from the l main portions of the record-slips.

The primary object of the present'invention is to provide an improved product of the character mentioned and an improved method of manufacture. The improved product vhas the margins of the slips bound together in such manner as to avoid undue bulkiness and stiffness at the bound edge.

A further object of the invention is to make the sets of forms from continuous-form fanfold stationery which is provided at its lines of folding with cut-out portions so that adhesive may reach the interleaved carbons therethrough and hold the same without resorting to the use of staples or other fastening means.

The invention is illustrated in a preferred em- 'bodiment in the accompanying drawings, in which- Figure 1 is a broken plan view of a printed and perforated web prior to its being fanfolded; Fig. 2, a broken perspective View of a unit comprising several sets of forms, partially fanfolded;

Fig. 3, a broken perspective View of the same after carbon-strips have been introduced; Fig.

4, a broken perspective view of a unit prior to 40 the application of adhesive along its binding edge;

Fig. 5, a broken perspective view of a stack of units after the application of adhesive material; Fig. 6, a plan view-of a finished set of forms;

Fig. 7, a broken sectional view, taken as indicated at line 7 of Fig. 6; and Fig. 8, a diagrammatic view showing a modified way of applying the adhesive in a continuous process.

In the embodiment illustrated, A designates a web of continuous-form stationery; B, carbon- 'k strips which are adapted to be interleaved between the folds of the stationery after being fanfolded; and C, glue or other adhesive used to bind the edges of the set.

The web A may comprise any desired number 56 of strips (four being shown for the purpose of 1932. Serial No. 638,021

illustration) which are printed alternatively on opposite sides so that the printed face will be on the upper side after the web has been fanfolded. The web is provided, between the strips, with longitudinal folds, or lines of weakening, to facilitate the fanfolding operation. Those lines which occur at the top portion of the printed form are designated 10 and are provided with adhesive-admitting perforations or cut-out p0rtions 11. The longitudinal line at the bottom portion of the forms is designated 12. Additional parallel lines of weakening 13 are spaced equidistant fro'm the fold of lines 10. Preferably, the printing is done on cylinder printing presses, and the lines 10, 12 and 13 are provided by means of a scoring operation. The apertures 11 may be made by means of punches mounted on the printing rolls, if desired.

As the web A leaves the printing\press, it is fanfolded into the form shown in Figs. 2 and 3 in the well-known manner.

The carbon-'strips B preferably are provided with an uncarbonized marginal portion 14 which is better adapted to contact the adhesive C. The carbon-strips are of less Width than the printed forms, designated generally as 15, so that the lower marginal portions of the latter will project beyond the lower edge of the carbon-strips. This provides each form with a marginal finger grip 16. The carbon-strips may be fed into interleaved relation with the fanfolded web from opposite sides by angular turn-plates or other means (not shown). The carbon strips are so positioned Within the web A that they are in superposed relation with their top edge substantially ush with the lines of fold 10. -It will be understood that a portion of the uncarbonized area 14 will be exposed through the cut-out portions 11 which were provided in the lines of fold 10. The loaded strip may then be cut into unit lengths comprising any desired number of forms, preferably three or four in number. These units may then be placed in superposed relation and glue or other adhesive applied along the uppermost edge of the unit, as illustrated in Fig. 5. The units are then separated and the lower edges of the forms including the line` of fold 12 are trimmed off to free the lower edges of the strip. The unit may then be out up into individual sets of forms which are ready for use.

In the gluing operation, a certain amount of the adhesive material will enter the-perforations 11 and cause the exposed portion of the carbonstrip 14 to adhere to the adjoining record-slips, as best shown in Figs. 6 and 7. A certain amount of the adhesive may get through the lines of weakening 10 and further assist in holding the carbon-slips. Obviously, the line 10 may comprise a perforate line, in which case the cut-out portions ll will not be needed.

It will be understood that the record-slips l5 are held in the set by the integrally formed binding 17 which is readily detachable along the line of weakening 13.

In the modification shown in Fig. 8, the adhesive C is applied to the binding edge of the loaded strip, as it leaves the carbon interleaving apparatus, by means of a rotary brush 20 which dips into a glue pan 21. By employing this expedient, the process is made continuous and the strip may be trimmed at one edge and cut into individual sets of forms as soon as the quick-drying glue has had an opportunity to set.

The forms are particularly adapted for use in typewriters, Elliott-Fisher machines, and the like. The binding edge is free from staples and other bulky projections so that it may readily be fed around the platen of a typewriter. As only a small amount of glue is applied to each set of forms, the binding edge is quite flexible.

The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.

VJhat I regard as new, and desire to secure by Letters Patent, is:A

l. A method of making manifold sets of forms which comprises: forming a web which comprises the record-slips of a set of forms with a line of folding having adhesive-admitting perforations thereat and lines of weakening in said slips parallel with and on opposite sides of the line of folding, thus providing marginal binding-strips; folding the web along the line of folding; introducing a relatively n'arrow transfer-slip between said record-slips; and applying adhesive at the line of folding and through the adhesive-admitting perforations thereat.

2. A method of making manifold sets of forms which comprises: forming a web Vwhich comprises at least four record-slips of a set of forms connected by lines of folding; punching adhesiveadmitting perforations in alternate lines of folding, and scoring longitudinal lines of weakening in said slips near and on opposite sides of said alternate lines of folding to form binding-strips; fanfolding the web so that said alternate lines of folding are in superposed relation; introducing relatively short transfer slips between the recordslips; and adhesively connecting the slips at the lines of folding mentioned, the adhesive being partially entered through said adhesive-admitting perforations.
